Deal on Joe Biden's $2 trillion plan edges closer; Kamala Harris is 'confident'

She told reporters back at the Capitol that more than 90 per cent of the package was agreed to: The climate change components of the bill ''are resolved,'' but outstanding questions remained on health care provisions.

Vice President Kamala Harris sounded even more certain. On a visit to New York City, she said tensions often rise over final details but ''I am confident, frankly -- not only optimistic, but I am confident that we will reach a deal.''

No agreement was announced by Friday's self-imposed deadline to at least agree on a basic outline. Biden wants a deal before he leaves next week for global summits in Europe.

Pelosi hoped the House could start voting as soon as next week, but no schedule was set.

Sticking points appear to include proposed corporate tax hikes to help finance the plan and an effort to lower prescription drug costs that has raised concerns from the pharmaceutical industry. Democrats are in search of a broad compromise between the party's progressives and moderates on the measure's price tag, revenue sources and basic components.

At the White House, the president has ''rolled up his sleeves and is deep in the details of spreadsheets and numbers,'' press secretary Jen Psaki said.

Biden was to spend the weekend at his home in Wilmington, Delaware.

Psaki compared the work to starting Social Security and other major federal programs decades ago, then building on them in following years.

''Progress here is a historic package that will put in place systems and programs that have never existed in our society before,'' she said, noting the effort to expand child care and provide free prekindergarten for all youngsters.

Negotiations are proceeding as Biden more forcefully appeals to the American public, including in a televised town hall, for what he says are the middle-class values at the heart of his proposal.

In a Senate that is evenly divided between the Democrats and firmly opposed Republicans, Biden can't afford to lose a single vote. He is navigating his own party's factions — progressives, who want major investments in social services, and centrists, who prefer to see the overall price tag go down.

''When you're president of the United States, you have 50 Democrats — every one is a president. Every single one. So you gotta work things out,'' he said during a CNN town hall Thursday.

Still, he expressed optimism about the process. ''It's all about compromise. Compromise has become a dirty word, but bipartisanship and compromise still has to be possible,'' he said.

On one issue — the taxes to pay for the package — the White House idea seemed to be making headway with a new strategy of abandoning plans for reversing Trump-era tax cuts in favor of an approach that would involve imposing a 15 per cent corporate minimum tax and also taxing the investment incomes of billionaires to help finance the deal.

Biden has faced resistance from key holdouts, in particular Sen. Kyrsten Sinema, D-Ariz., who has not been on board with her party's plan to undo President Donald Trump's tax breaks for big corporations and individuals earning more than USD 400,000 a year.

The president was unusually forthcoming Thursday night about the sticking points in the negotiations with Sinema and another Democrat, conservative Sen. Joe Manchin of West Virginia.

While the president said Sinema opposed raising ''a single penny in taxes'' on the wealthy or corporations, a White House official later clarified that the president was referring to raising the top tax rates, not the range of tax proposals ''which Sen.

Sinema supports.'' If so, that could unlock a key piece of a deal. With a better understanding of the revenues available, Democrats can then develop a topline amount of spending for the package, and adjust the duration and sums for various programs accordingly.

Biden said Manchin doesn't want to ''rush'' the transition to clean energy so quickly it will result in major job losses in his coal-producing state.

Even still, Biden acknowledged major reductions to his original vision. He signalled the final plan would no longer provide free community college, but said he hoped to increase Pell Grants to compensate for the loss of the policy.

He also said that what had been envisioned as a federally paid, months-long family leave program would be just four weeks.

Another work in progress — the idea of expanding Medicare to include dental, vision and hearing aid benefits for seniors, is a priority for Sen. Bernie Sanders, the independent of Vermont. Biden said he likes the idea, but with Manchin and Sinema objecting, the proposal is ''a reach.''
